Default Vitara Wiring in spot lights, relays ..... PLEASE HELP!

1stly start by saying i have a 1993 suzuki vitara, its a spanish import, 8v fuel inj and i live in england! .....

Right, well on my mission to light up the whole of my city I started to wire in my spot and fog lights yesterday and I’ve run in to a problem that I think could be one or two things but thought id ask to see if I can get either confirmed or indeed any other ideas!

Basically I wanted my lights so I could have a on/off switch that would turn the whole lot on and off, and separate switches for each set of lights! On top of that I wanted to wire in a relay on a switch so that when the switch is off, it makes no difference and the lights come on when you switch each switch on or off, but when the relay switch is on, its connected to my full beams so when my full beams are on, my lights that have been selected will come on aswell…..

So my idea was this,….

To have the control box to look like this,…..



Switch A = On/Off switch for the whole lot
Switch B = Relay switch On/Off
Switch C = Fog lights
Switch D = Spot lights
Switch E = Will be roof lights (haven’t got them yet but thought id wire it in now to save less hassle for later on)

And id wire it up like this,….



The lights worked as planned when the relay switch was off (black Circuit in picture) each set of lights turned on and off at there switches and turned on and off completely at the main switch!

The problem is when I switch it to the relay side (red circuit) (hahahahaha I’m typing this in word and did you know it even does smiley’s?) Anyway… they just work like the black circuit and my main beam has absolutely no say in it! Only the control box

Problems I think it could be…

Now on the Relay instructions…(scanned them in)….



… it says connect pin 86 to the main beam,… well I taped in to the main beam wire right next to the bulb. I think this may be a problem as I took the control box out and connected just the relay to the spots and they stayed on, again, main beam stalk thingy had no say in this (lol there it is again). I then took the relay out and attached the positive wire of my spotlights to the wire that cut in to the full beam wire and they lit up again (with full beam on and off) so maybe iv wired the wire in to the full beams in the wrong place? Where should it be wired?

I also noticed that when I switch the wires from pins 85 and 86 on the relay, it still lights up the same!



2nd problem I thought t could be is the control box,….

I bought toggle switches with 6 pins on them,…. Can be used as just on/ff, or a kind of “one or the other” kind of switch, so if its in one direction,… say the off, it still goes through to the other switches (black side on the circuit diagram) and if the switch is in the on position, it goes through the relay side (red side)

Now its wired up like this,…..





Now I understand that’s going to be a bitch to work out, so I drew it on the pc to make things a lil easier!



I drew it so your looking directly behind them, so The on off switch is the 1st on the right, The one left of it is the relay switch, the one left of that is fog light switch, and the one left of that is the spot light switch!

I also included the relay

I wonder because I’ve attached the blue wires together (blue wires are still positive, just used them as I was running out of red wire) that will go to each set of lights, regardless of weather relay switch is on or off, it still makes a circuit?



I’m sorry that this is a bit of a read but thought if I be as detailed as I can so id get a better answer… this is the 1st time I’ve tried wiring a relay in to a circuit for lights, and I think its going to be the last

Thanks for any Help

Your problem is in the "relay coil control" side of the circuit - pins 85 & 86 - and it is caused by how Suzuki wires the headlights.

Your wiring would work on most vehicles, but not on a Suzuki - because Suzuki switches the headlight grounds and not the +12V feeds.

Try wiring 85 to the battery positive (or jumper to pin 30) and see what happens.

Also - it might be an idea to add some fuses to your circuit - wouldn't want a short to burn the truck down, would we?

Hey was just coming on here to say i was trolling around on here and just found out (providing i read it right) that the main and full beam are always live and the switch is on the Negative/ground wire,....

which, is some kind of relief, but at the same time, is really spinning me out! it would explain why when I hook the positive wire of the spots and the wire I used to tap in to the full beams, it lights up the spot lights!

however I cant get my head around the switches on the ground of the headlight and how it'd determine which beam to light up!

and yeah I have fuses, I just never put them in diagrams just to keep it a lil more easy on the eyes

Thank you for the help so far,....

got a few things im guna try out tonight in hope that somthing may work
